Hi everyone,

I was trying to compile the Quantlib Addin on my laptop (OS: Windows XP SP2; Visual Studio 2005 express) and i just got a funny problem:

------ Build started: Project: AddinExcelStatic, Configuration: Debug Win32 ------

Linking...

Creating library .\buildStatic\vc80\Debug/QuantLibAddinStatic-vc80-mt-sgd-0_3_12.lib and object .\buildStatic\vc80\Debug/QuantLibAddinStatic-vc80-mt-sgd-0_3_12.exp

 it just looks like I have some problems with the linker. Having a look around on internet I found out it might be related to a problem importing a c function in a c++ project without using the 'extern "C" ' statement ( http://blogs.msdn.com/vsdteam/archive/2005/11/20/495123.aspx). Is it correct? if it is so, where do I have to modify the code?
